1. Data Availability Statement 
The data for this publication have been collected in a project that has compiled a large set (and combination) of children’s abilities, preferences, and family (socio-demographic) characteristics (see Sections 1.3 and 1.4 of the Online Appendix), and thus represents highly sensitive data. This dataset cannot be made available for data protection reasons. In addition, parental consent for data usage only covers strictly scientific purposes. The restriction to scientific purposes was also necessary to comply with data protection requirements and use of the data for strictly scientific purposes cannot be guaranteed if the dataset is made (publicly) available. Not all the data collected in this project are analyzed for this publication, see Section 1.4 of the Online Appendix for details. Researchers interested in replicating our findings can get access to the data set after filling out a research agreement with our universities. The code replicating the tables and figures in this article can be found in the Harvard Dataverse, https://doi.org/10.7910/DVN/PQNQU0. We confirm that in the paper and the Online Appendix, we have reported all measures, conditions, data exclusions, and how we determined our sample sizes. 

2. Replication Code
All necessary code to replicate our findings can be found in the file "Replication Do File WMT.do" as part of this online repository. 


3. Replication of Findings
Once access to the data set is enabled (see above), all findings can be replicated using the code of the do file in this repository.
